Malocclusion.
Less than ideal interarch occlusal relationships rarely if ever cause significant untoward effects on the masticatory system. Parafunctional habits (such as bruxism and clenching) are responsible for excessive occlusal wear, fractured teeth, tooth mobility, the periodontal lesion of trauma from occlusion, fractured restorations, myofascial pain involving the muscles of mastication, and painful TMJs. Correction of the malocclusion with orthodontic procedures, restorative procedures, or occlusal adjustment by selective grinding will not control the parafunctional habits. Myofascial pain originating from the muscles of mastication is in an overwhelming number of cases a self-limiting problem. Therapy for this problem should not bring about any permanent physical changes to the patient's interarch occlusal relationships.
